I think Williams have just released the image as a rendering of the nose and not a finalised chassis with colours and sponsored on board. Best to see the final version heels, I think. In previous years I've loved the retro-styling of their numbers on the sidepod and wouldn't be surprised if this car evokes the mid-late 90s colour schemes.

Sith, I think it'll be interesting to see and Jenson Button was predicting chaos. There shouldn't be turbo lag due to the revs being so high, but we will see.

But to be fair, that advantage hasn't materialised thus far except in terms of mechanical reliability. The Jerez tests will be nothing more than exercises in seeing if the cars work more than who has the best race package. That we've had Kimi, Jenson and rookie Magnussen top the days testing does not mean we should expect these people to be race winners come Melbourne.

Ricciardo, sadly, failed to run yesterday due to the same issues which kept Vettel off track.

I'd certainly like to see them brought back to the pack, and have at least 3-4 teams competing for the title. It sounds as though RB have dropped even further than that, though, now behind Ferrari and Mercedes. I would be nice to have a season where multiple cars are competing, rather than just 1 or 2.

yeah. there are enough quality drivers out there, as evidenced by the number of ex-world champs competing, so it's a shame when the mechanics aren't there across the teams to help fascilitate competition. i haven't been following it too closely, but who has looked the quickest in the pre season?

Williams posted the best time overall, in Massa. But Mercedes engines have been the constant factor in speed - Hulkenberg and Perez in the Force India, Hamilton and Rosberg in the Merc, and Button and Magnussen in the McLaren have all had great runs.
